I need to seperate 1 input line into 4.

My program directs me to have the user input 1 input line containing 4 rational numbers representing, length, width, thickness, and weight. They will be seperated by commas.

For example:

4, 4, .009, .0015

I then have to take those values and make various If statements to group them into the right category.

What I need help on is splitting the input line into 4 values. Is there some class, part of java.lang.object? Is it stringtokenizer?

ASAP please. THANKS!

you can use the stringtokenizer class or simple read the user input as a String and call its split method

Code:

---

String s = "4, 4, .009, .0015";
String separated[] = s.split(',');

---

that will also leave you withe the white space after each comma, just trim() each array element to remove them

If the OP has JDK 1.5 installed s/he can use the Scanner class for this as well:
http://java.sun.com/j2se/1.5.0/docs/...l/Scanner.html

And the String.split(...) method takes a String as parameter (regex String to be precise).
;')

like prometheuzz said, the split( String ) method takes a String, not a char.

Code:

---

String s = "4, 4, .009, .0015";
String separated[] = s.split( ", " );

---

I added a space btw, so that it's split up into:
separated[1] = "4", separated[2] = ".009", etc. instead of them being equal to " 4" and " .009"

I wouldn't garauntee on there being spaces after every comma. I'd split by just the comma then use trim() if a possible whitespace was an issue.

yeah good call. :p

Code:

---

String s = "4, 4, .009, .0015";
String separated[] = s.split( "," );
               
for (int i = 0; i < separated.length; i++) {
        separated[i] = separated[i].trim();
}
